Our seals are engineered for durability, precision fit, and consistent performance under real-world testing conditions.
Electrical Test Connectors and Harnesses
Our electrical test harnesses and connectors are engineered for accurate, repeatable sensor testing on engines and transmissions. Each connector is custom designed and molded from durable urethane to withstand demanding test environments and high cycle use.
We utilize replaceable pogo pins to ensure reliable electrical contact with sensors while minimizing wear and simplifying maintenance. The result is a robust, precision-fit solution that delivers consistent performance and long-term durability in critical testing applications.
ECM/TCM Programming Pods
Our ECM and TCM programming pods are built for reliable, high-performance communication during engine and transmission control module testing. Each pod is custom designed to match your specific application, ensuring precise alignment and secure connections throughout the programming process.
Constructed with durable urethane molding, our pods are designed to withstand repeated use in demanding environments. Integrated replaceable pogo pins provide consistent electrical contact while simplifying maintenance and extending service life—delivering dependable performance across every programming cycle.
